A few years ago, someone figured out small, cheap ARM Linux boards are really, really useful, extremely popular, sell very well, blink LEDs, and are able to open the doors of engineering and computer science to everyone. There is one giant manufacturer of these cheap ARM Linux boards whose mere mention guarantees us a few thousand extra clicks on this article. There are other manufacturers of these boards, though, and there is no benevolent monopoly; the smaller manufacturers of these boards should bring new features and better specs to the ARM Linux board ecosystem. A drop of water in a tide that lifts all boats. Something like that.

This week, Orange Pi, not the largest manufacturer of these small ARM Linux boards, has released two new boards. The Orange Pi Zero is an inexpensive, quad-core ARM Cortex A7 Linux board with 256 MB or 512 MB of RAM. The Orange Pi PC 2 is the slightly pricier quad-core ARM Cortex-A53 board with 1 GB of RAM and a layout that can only be described as cattywampus. We all know where the inspiration for these boards came from. The price for these boards, less shipping, is $6.99 USD and $19.98 USD, respectively.

The Orange Pi Zero uses the Allwinner H2 SoC
26-pin bank of pins is compatible with the first version of the board you’re thinking about
Also on board the Orange Pi Zero is WiFi provided by an XR819 chipset, Ethernet, a Mali400MP2 GPU, USB 2.0, a microSD card slot, and a pin header for headphones, mic, TV out, and two more USB ports.

The significantly more powerful Orange Pi PC 2 sports a quad-core ARM Cortex-A53 SoC coupled to 1 GB of RAM. USB OTG, a trio of USB 2.0 ports, Ethernet, camera interface, and HDMI round out the rest of the board.

[Slider2732] got his Orange Pi Zero working with a 3 watt amplifier, wireless keyboard (with built-in mouse), and car reversing monitor. But he needed a case to house it in. He remembered that he used to make parameters for ghost hunting by filling PC mouse cases with all sorts of electronics. So why not put the Orange Pi Zero in a mouse too? Looking through his mouse collection, he picked out an old Logitech optical mouse and went to work.

What’s smaller than a Pi Zero that will also run the armbian Linux distribution, OpenELEC Mediacenter, Kodi and a bunch of games?
